Panel to display n days before data based upon time picker selected

Hi, Am trying to have two panels with one showing the data corresponding to the range selected in time picker and the other panel showing data for the same time range but 7 days earlier. Have tried using eval to assign the 7d time range into tokens (after searching online). Time-15mnowrelative_time(relative_time(time(), "$earliest$"), "-7d")relative_time(relative_time(time(), "$latest$"), "-7d") Have added the tokens initialized weekearliest and weeklatest as token based search in another panel but it doesnt seems to work, $weekearliest$$weeklatest$ Can kindly provide pointers to check on how to implement them?
